In 2013, Radium introduced the first-generation Fuel Cell Surge Tank (FCST) — a drop-in system that quickly became the preferred fuel setup for professional racing teams worldwide.\u003c\/p\u003e\n\n\u003ch3\u003eWhat Is the FCST?\u003c\/h3\u003e\n\n\u003cp\u003eThe FCST is a complete drop-in fuel pump system designed for Radium Engineering fuel cells or any cell using the industry-standard 6×10, 24-bolt fill plate bolt pattern. Unlike a basic trap door or baffle box, the FCST features a true dual-chamber fuel tank with a single lift pump and up to three surge tank pumps — all packaged inside the fuel cell. It delivers all the benefits of a traditional external surge tank without the plumbing complexity or safety concerns.\u003c\/p\u003e\n\n\u003cp\u003eThe \u003cstrong\u003e20-0695-00\u003c\/strong\u003e variant is supplied without pumps and is designed for use with a mechanical fuel pump or inline electric pump(s). One or two -10AN (5\/8\") fuel pickups are used inside the surge tank, each fitted with an 80-micron filter. If two pickups are used, the 20-0737 Distribution Block is recommended for pumps with a 12AN inlet.\u003c\/p\u003e\n\n\u003chr style=\"margin: 20px 0; border: 0; border-top: 1px solid #000;\"\u003e\n\n\u003ch3\u003eCompatibility Requirements\u003c\/h3\u003e\n\n\u003cp\u003eTo install the FCST into a fuel cell, the following criteria must be met:\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eCell must have the industry-standard 6\"×10\" 24-bolt flange opening\u003c\/li\u003e\n  \u003cli\u003eOpening must be on the \u003cstrong\u003etop face\u003c\/strong\u003e of the fuel cell (not a side face)\u003c\/li\u003e\n  \u003cli\u003eCell depth must be at least \u003cstrong\u003e7.7\" (196mm)\u003c\/strong\u003e measured from the outer top face to the internal bottom face\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr style=\"margin: 20px 0; border: 0; border-top: 1px solid #000;\"\u003e\n\n\u003ch3\u003eStandard Fittings\u003c\/h3\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePUMP OUT - -8AN Male:\u003c\/strong\u003e External pump outlet port (engraved \"PUMP OUT\").
